AI Technical Summary

Benefits of technology

"The invention is a new outlet assembly for cartons that improves on previous designs. It consists of two members: a flanged member sealed to the inside of the carton with an outlet formation that projects through an outlet hole in the carton, and a cap member mounted on the outside of the carton. The cap member has a cover formation that fits over the outlet formation of the flanged member. The cover formation is sealed to the detachable portion, so when the cap member is removed, the detachable portion is torn away, opening the carton. This design ensures that the liquid from the carton is sealed off from the raw edge of the paperboard, preventing any negative effects on the product. The invention is cost-effective and efficient in providing a reliable and safe outlet assembly for cartons."

Problems solved by technology

Accordingly, if this edge is uncoated or unsealed, the liquid from the carton would be exposed to the raw edge of the paperboard, which would be unacceptable, since if it were milk it would sour and other products deteriorate.

Embodiment Construction

[0027]FIGS. 1A-3C show an outlet assembly 1 made, for example, of plastic, and comprising a flanged member 2 and a cap member 3. The flanged member 2 in this embodiment resembles a hat and has a projecting outlet formation and a brim or flange. The outlet formation on the flanged member 2 has a score or fault line 5 on the top of the outlet formation defining a detachable member 4 like a breakaway tip. The detachable member 4 is that portion of the outlet formation that is inside the score or fault line 5. The score or fault line 5 may be a continuous or broken line of thinned material, creating an area of weakness at which the material may be easily torn.

[0028]The cap member 3 has a cover formation that generally fits over the outlet formation of the flanged member 2. An inner surface of the cover formation is sealed to the outer surface of the detachable member 4. It will be appreciated that the seal between the inner surface of the cover formation and the outer surface of the det...

Abstract

An outlet assembly for a carton is provided, comprising a flanged member sealably attached to an interior side of the carton, the flanged member having an outlet formation that projects through an outlet hole in the carton, and a cap member mounted on an exterior side of the carton, the cap member having a cover formation that generally fits over the outlet formation. The outlet formation has a detachable member. An inner surface of the cover formation is sealed to the detachable member, such that when the cap member is lifted from the outlet formation, it tears away the detachable portion from the remainder of the outlet formation, thereby forming an outlet opening for the carton.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to U.S. provisional application Ser. No. 60 / 935,622 filed Aug. 22, 2007, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The invention is directed to an improvement in outlets for sealed containers, such as the outlets that are used in cartons for milk, juice, and the like.[0003]Milk, juice and other liquids are commonly supplied in gable top cartons having an outlet assembly in the form of a plastic screw-on cap combination. The outlet assembly has a threaded nozzle member sealed onto one of the slanted gables of the carton and an unattached screw-on cap. This screw-on cap combination is injection molded and is costly to make and to install.[0004]More specifically, these outlet assemblies commonly consist of a threaded screw on plastic cap member threaded onto a threaded outlet member having a detachable portion. The threaded outlet member...
